Highly effective silicone-based defoamer for rapid foam knockdown and sustained foam control.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, and styrene-butadiene emulsions.
Low dosage requirement—typically effective at 0.05–0.3 wt% active in final formulation.
Thermally stable up to 120 °C, supporting high-temperature processing conditions.
Non-yellowing and low-volatility, ensuring formulation stability and minimal impact on product aesthetics.
Architectural coatings (e.g., interior/exterior paints and primers).
Industrial maintenance coatings and protective coatings.
Adhesives and sealants, particularly waterborne acrylic and latex formulations.
Construction chemicals, including cementitious tile adhesives and self-leveling underlayments.
Textile and paper coating applications requiring low-foam processing.
